Key result
Open irrigated-tip catheters for atrial flutter ablation reduced transient isthmus block compared to solid 8-mm-tip catheters (12 vs 23 patients, P=0.03) and shortened procedure times (P=0.002).
Why the study?
Does radiofrequency ablation using an open irrigated-tip catheter improve procedural outcomes compared to a solid 8-mm-tip catheter in patients with typical atrial flutter?
Population
130 consecutive patients with typical atrial flutter (AFL), mean age 61 +/- 11 years, 104 men.

May support irrigated-tip use for AFL ablation in experienced centers; leaves open need for larger RCTs on long-term outcomes.

Absolute Event Rate: 100% vs 100%
Open irrigated-tip catheters are more effective than solid 8-mm-tip catheters for atrial flutter ablation, reducing procedure times and the incidence of transient isthmus block.
Ventura et al. (2004) conducted an RCT in typical atrial flutter (AFL) (n=130). Open irrigated-tip catheter vs. Solid 8-mm-tip catheter was evaluated on Bidirectional conduction isthmus block. Open irrigated-tip catheters for atrial flutter ablation reduced transient isthmus block compared to solid 8-mm-tip catheters (12 vs 23 patients, P=0.03) and shortened procedure times (P=0.002).
